ABSTRACT:
A method of control of a car air-conditioner which prevents condensation and fogging on window glass occurring at the initial start of a slow starting heat pump system, without dehumidification by a large amount of ventilation as in the past, by driving an absorbent fan simultaneously with the start of a heating operation by the system so as to remove the moisture from the air in the passenger compartment by a small amount of an absorbent, starting a low level of ventilation when the heat pump system has finished warming up, ending the dehumidification by the absorbent within a relatively short time, and starting the regeneration of the absorbent by supplying power to a heater.
